Transcriptional Profiling Identifies Potential Genes Associated With Multiple Biotic Stresses In Arabidopsis, Hibatullah Mustafa Al Ashram
Transcriptional Profiling Identifies Potential Genes Associated With Multiple Biotic Stresses In Arabidopsis, Hibatullah Mustafa Al Ashram
Biology Theses
Plants are exposed to many environmental stresses that affect their growth and development. These stresses include biotic stresses (organisms) and abiotic stresses (drought and salinity). Plants respond to these stresses by transcriptional reprogramming and different signaling pathways. Arabidopsis thaliana had shown great sensitivity to the biotic stress: Botrytis cinerea, Alternaria brassicicola, Pseudomonas syringae and the herbivore insect Pieris rapae. The overall goal is to identify common regulated genes that respond to all these biotic stresses to ultimately improve plant stress tolerance in Arabidopsis. The specific aims are to: (1) determine the regulated genes in response to an …

A Novel Transcription Factor In Arabidopsis Thaliana Abiotic Stress Response, Achira S. Weerathunga Arachchilage
University of New Orleans Theses and Dissertations
Plants respond to environmental stress by altering their gene expression. Under stress conditions some genes are activated and some genes are repressed. Even though a lot of work has been done to understand mechanisms of gene activation under abiotic stress very little information is available on how stress responsive genes are kept repressed under normal growth conditions. Recent work has revealed that plants use transcriptional repression as common mechanism of gene repression. Transcriptional repression is achieved by recruitment co-repressor complexes to the target genes. Recent studies have revealed that the co-repressor LUH complexes with SLK1 and SLK2 to silence Arabidopsis …

Uncovering The Molecular Link Between Mir156.Spl15 And Carotenoid Accumulation In Arabidopsis, Davood Emami Meybodi
Electronic Thesis and Dissertation Repository
Carotenoid Cleavage Dioxygenases (CCDs) are an enzyme family that cleaves specific double bonds in carotenoids. MicroR156 in Arabidopsis regulates a network of genes by repressing 10 SPL genes, among which, SPL15 was found to regulate shoot branching and carotenoid accumulation. The expression of CCD1, CCD4, CCD7, CCD8, NCED2, NCED3, NCED5, NCED6, NCED9 and SPL15 was evaluated in siliques at 10 days post anthesis and in 10-day-old roots in Arabidopsis wild type, sk156 (miR156 overexpression mutant), RS105 (miR156 overexpression line), spl15 (SPL15 knockout mutant) and two 35S:SPL15 lines. Results showed that most of CCD/NCED genes were …
